According to the device, needed lenses can be conveniently and rapidly selected, the lenses can be conveniently and rapidly discharged, meanwhile, the lenses can be conveniently and stably conveyed, the lenses can be conveniently clamped in the inspection pipe, the lenses are firmly fixed, the fixing precision is higher, replacement of the lenses is more automatic, and the lenses are better protected.

Description

technical field [0001] The invention relates to the field of retinoscopy and optometry, in particular to a retinoscopy and optometry device used for ophthalmology and optometry teaching. Background technique [0002] The full name of retinoscopy optometry is retinoscopy, which is an objective optometry method. Through the retinoscope, a beam of light is projected to the refractive system of the patient's eye to reach the retina, and then the reflected light from the retina reaches the retinoscope, passes through the peephole of the retinoscope, and is observed by the optometrist. This retinal reflected light is the "red light reflex", which is the main basis for retinoscopy analysis. The forward movement and reverse movement formed by the red light reflection are also different according to the different refractive states of the patients. The optometrist analyzes the different motions and removes the corresponding lenses from the standard lens box to eliminate the motions ...
